Abstract
An adhesive-sheet for the reinforcement of metal plate, and a method of reinforcing metal plates using an adhesive-sheet, are described. The adhesive-sheet comprises a first epoxy resin composition layer and a second epoxy resin composition layer laminated thereon wherein the first epoxy resin composition layer, when cured by heating, has a modulus of elasticity in tension sufficient to increase the stiffness of the metal plate, whereas the second epoxy resin composition layer, when cured by heating, has a modulus of elasticity in tension insufficient to increase the stiffness of the metal plate.
Claims15
An adhesive-sheet for the reinforcement of metal plate, comprising a first epoxy resin composition layer and a second epoxy resin composition layer laminated thereon wherein the first epoxy resin composition layer is prepared so that when provided on the metal plate and cured by heating, it has a modulus of elasticity in tension sufficient to increase the stiffness of the metal plate, and the second epoxy resin composition layer is prepared so that when provided on and adhered to the metal plate and cured by heating, it has a modulus of elasticity in tension insufficient to increase the stiffness of the metal plate.
A method for reinforcing a metal plate comprising applying thereto an adhesive-sheet comprising a first epoxy resin composition layer and a second epoxy resin composition layer laminated thereon, wherein the first epoxy resin composition layer is prepared so that when provided on the metal plate and cured by heating, it has a modulus of elasticity in tension sufficient to increase the stiffness of the metal plate, and the second epoxy resin composition layer is prepared so that when provided on the metal plate and cured by heating, it has a modulus of elasticity in tension insufficient to increase the stiffness of the metal plate, in such a manner that the second epoxy resin composition layer comes into contact with the metal plate, and, thereafter, curing the adhesive sheet by heating.
